This is based on habo recent uploaded thing:12116 . Nudel_P made a comment about an openscad version... So I decided to do it.

I have no 3d printer yet, so not sure what size I should make the attached stl file. Let me know and I'll update the public stl file, or you can generate your own set from the openscad file.

I've put 'generator' in quote because you need to provide the pattern... so it doesn't generate the puzzle, just the 3d render of the provided pattern. It be great if someone can comeup with a pattern generator. That a bit over my head.

Pattern start from the top left and rotate clockwise.
